IMPROVEMENT IN LAMP-EXT INGUISHERS.

Specification forming part of Letters Patent No. 160,988, dated March16, 1875 application filed February 16, 1875.

To all whom it may concern:

Be it known that I, Prof. WM. H. ZINEMIER- MAN, of Washington College,Ohestertown, in the county of Kent and State of Maryland, have inventeda new and Improved Lamp-Extin guisher; and I do hereby declare that thefollowing is afull, clear, and exact description of the same, referencebeing had to the accompanying drawing forming a part of thisspecification, in Which Figure 1 is a side elevation, with burner insection; Fig. 2, modification of the flame-extinguishing tubes for flatburners; Figs. 8 and 4, modifications of the same for circular burners.

The object of this invention is to provide a means for extinguishinglamps in which the danger resulting from blowing down the chimney shallbe avoided, and which shall in every Way be more convenient andeffective. It consists in the combination, with the burner of a lamp, ofan elastic compressible air-chamber, and a tube for conducting thecurrent of air from the same to the wick in such a manner as to blow outthe flame without danger.

In the drawing, A represents a lamp having.

an ordinary Argand or circular burner, B. O is a metallic tube solderedto the burner at a. Said tube is extended outside the burner to form aconnection for an elastic tube, D, and is connected inside the burnerwith'a detachable quencher-tube, O, which terminates at its upperextremity, just above the burner, in a closed end having acircumferential row of small perforations, -b, upon a level with thewick. These said perforations form vents, which direct a series ofradial blasts of air upon the burner for the purpose of extinguishingthe flame, the vents being so arranged as to blow the flame directlyaway from the wick, and thereby avoiding the danger consequent uponblowing the flame downwardly.

I do not confine myself to the tube as thus described, for. it isobvious that for differentshaped burners differently-shaped tubes arenecessary. I may, therefore, use a tube with an open end, having abovethe opening a cap or disk for making a continuous radial blast, as shownin Fig. 4; or I may use for flat burners any of the modifications shownin Fig. 2, in which S is a branched tube; S, a T-shaped tube with a slitin the cross-piece, and S a T- shaped tube with a row of perforations inthe cross-piece.

By making the tube as shown in Fig. 4 the cap or disk may be so arrangedupon supports within the tube as to be adjustable to regulate the natureof the blast. For the sake of classification, I call all these tubesquenchers.

E is a hollow rubber ball attached to the elastic tube D, and forming anelastic air-chamber, which, when compressed, forces a current of air upthe burner and upon the wick, in the manner described, the elasticity ofthe ball being sufficient, when liberated, to cause it to resumeit'soriginal shape.

By means of the above-described arrangement any lamp may be providedwith means of extinguishment which are at once simple, safe, andconvenient, the device being admirably adapted to high swinging lamps,out of convenient reach, in which case the tube may be extended so as tobring the air-chamber within a convenient distance.

In the application of my invention I do not confine myself to the rubberball, as shown, but may use any elastic compressible air-chamber.

Having thus described my invention, what I claim as new is 1. Thecombination, with a lamp burner, of an elastic compressible air-chamberand a tube for conducting a current of air to the Wick for the purposeof extinguishing the lamp, substantially as and for the purposedescribed.

2. The combination, with the burner B, of a tube, 0, soldered to thesame, and a detachable tube, O, having a circumferential row ofperforations, b, substantially as and for the purpose described.
